Morning Boot Issue

Aug/Sep 2022 - DVR + 3x remote boxes

Most mornings over the last six weeks or so, we awake to find "boot" on the DVR and no TVs come on.  Only th "b" in boot is lit.  the letters "oot" are dim.

When this happens, SmartHelp and manual online reboot will not work.  

If you keep unplugging and plugging in the DVR and the remotes, at some point things work.  This is usually after an hour or two.

Cox support is zero help.  They had me take two of the remote boxes in for swap.  One because that TV (remote) is the first one we try, so they said swap that.  The second remote was swapped because it was an older model.

One of the two swapped boxes was DOA, so another trip back to Cox.  The system worked for a day, then the exact same failure.  Cox wanted to send a tech out, but I decided to take the DVR and move it to one of the remote TV sets.  That was to see if the problem followed the DVR.  After two days, same failure.

Is anyone else seeing anything like this?

  • Summary of my tests from 10/21/22 through 11/19/22:

    8 morning rebootings in 30 days and 2 failures to record properly even though DVR was not rebooting in the morning. TV was always turned off shortly after midnight until 8:00 am. 

    2 rebootings were after 4:00 am (4:02 am when recordings stopped early and one instance where no recordings were scheduled after the one that finished recording at 4:00 am)

    2 rebootings were prior to 3:59 am but exact time not known (those scheduled for 4:00 am & later did not record)

    4 rebootings were prior to 8:00 am (1 prior to 5:00 am, 1 prior to 6:00 am, 1 prior to 7:00 am, and 1 prior to 8:00 am). Starting at 7:00 am on day 1, I added a 1 hour earlier program to the schedule each day until every hour after 4:00 am had a recording.  None of these recorded and the DVR was rebooting every morning.

    One error when the DVR was working properly at 8:00 am was a recording scheduled for 4:00 am didn’t start until 4:33 am. A previous recording ended at the correct time of 3:15 am. There may have been another recording scheduled for 3:00 am to 4:00 am that failed to record, or I may have accidentally not scheduled it

    The second error when the DVR was working properly (not rebooting) was that none of the scheduled recordings from 1:59 am to 4:00 am were done. This was the only error on a Sunday morning (not a workday).  It wasn't the result of the end of daylight savings time which was the prior weekend and we didn't have a power outage (all our clocks were working).

    The only Saturday error was this morning when the scheduled 3:59 am 1 hour recording stopped after 1 min 36 sec. I had turned the TV off at 12:11 am and the failure happened at 4:01 am. This is 10 minutes less than the 4 hours of inactivity that puts the DVR into Power Saver mode which I turned off months ago suspecting that it was causing the rebootings.

    My conclusion is that the rebootings are caused by Cox doing updates between the scheduled hours of 2:00 am to 4:00 am. I would consider the Saturday early morning event to be an end of the Friday business day schedule. Do they do these every night or just periodically? And could they be started slightly before or after the schedule time frame?

    Or the cause could be that the DVR just hiccups now and then.
